Display device and method for manufacturing the same

Abstract

Disclosed is a display device. In accordance with the display device, before an organic stack of a light-emitting diode is formed, a sticker is attached to a substrate, while a camera hole-forming portion and a margin area around the same are present, to form the organic stack, and the sticker and components on top of the sticker, such as the organic stack, are removed, so that the edge of the organic stack can be aligned without any additional process using separate masks and the reliability of the display device can be improved due to the provision of the organic stack at a location spaced apart from the camera hole by the margin area.

What is claimed is: 
     
       1. A display device comprising:
 a substrate having an active area and an outer area surrounding the active area; 
 at least one camera hole in the active area of the substrate; 
 at least one light-emitting element spaced apart from the camera hole by a margin area in the active area, the at least one light-emitting element including an organic stack including at least one common layer and an organic light-emitting layer, and a first electrode and a second electrode respectively disposed below and on the organic stack; 
 a bank exposing a light-emitting part of the organic light-emitting layer; and 
 a bank pattern consecutively extending to the margin area from the bank in a same layer as the bank, 
 wherein an end of the organic stack is on the bank pattern and spaced farther than an end line of the bank pattern with respect to the camera hole. 
 
     
     
       2. The display device according to  claim 1 , wherein the organic stack comprises the organic light-emitting layer, a first common layer disposed below the organic light-emitting layer, and a second common layer disposed on the organic light-emitting layer,
 wherein the first common layer, the second common layer, and the second electrode are spaced apart from the camera hole by a same distance corresponding to the margin area. 
 
     
     
       3. The display device according to  claim 1 ,
 wherein the organic stack is provided in a portion of the bank pattern not overlapping the margin area and the organic stack is not provided in the margin area. 
 
     
     
       4. The display device according to  claim 3 , wherein ends of the organic stack and the second electrode are provided on a portion of the bank pattern not overlapping the margin area. 
     
     
       5. The display device according to  claim 2 , wherein the organic light-emitting layer is spaced farther apart from the camera hole than the first common layer. 
     
     
       6. The display device according to  claim 1 , wherein the organic stack and the second electrode are not provided in the margin area and have a same vertical tapers adjacent to the camera hole. 
     
     
       7. The display device according to  claim 1 , wherein the margin area comprises a dam pattern on the substrate. 
     
     
       8. The display device according to  claim 1 , wherein a sidewall of the camera hole is formed by the substrate and a plurality of inorganic layers on the substrate. 
     
     
       9. The display device according to  claim 8 , wherein an uneven portion is provided in at least one of the plurality of inorganic layers and substrate in the margin area such that the uneven portion is spaced apart from the camera hole. 
     
     
       10. The display device according to  claim 1 , further comprising an encapsulation stack covering the at least one light-emitting element on the substrate excluding the camera hole, and including at least one organic film and at least one inorganic film. 
     
     
       11. The display device according to  claim 10 , wherein the at least one organic film of the encapsulation stack is spaced apart from the camera hole in the margin area, and the at least one inorganic film of the encapsulation stack forms a part of a sidewall of the camera hole. 
     
     
       12. The display device according to  claim 11 , wherein the at least one inorganic film includes inorganic films on and below the organic film contacting the sidewall of the camera hole in a vertical direction. 
     
     
       13. The display device according to  claim 2 , wherein the first common layer, the second common layer and the second electrode cover a portion of the active area excluding a region including the camera hole and the margin area, and extend outwards to be provided in a portion of the outer area, and
 wherein the second electrode is a widest among the first common layer, the second common layer and the second electrode at the outer area. 
 
     
     
       14. The display device according to  claim 1 , further comprising a camera module inserted into the at least one camera hole at a rear surface of the substrate and wherein the camera module includes a camera lens introduced into the camera hole and a camera bezel supporting the camera lens.
